BK-16 switch unit (BK) is an input/output device for equipment not related to the hardware components (HWC)) of a robotic fire suppression system (RFSS).

BK expands the capabilities of the central control device control box (CB-CCD) for the input/output of discrete signals. BK and CB-CCD are connected via RS-485 interface.

BK functioning is determined by the configuration information and pre-settings of the CB-CCD.
